Why E300-arty with JTAG ID 0x20000913 failed to upload SPI?


Hello there,

My Arty board works fine with the SiFive E31-Arty evaluation image, so I assume my environment is okay.

I just cloned the latest source of freedom E300 and build the MCS and tested it with freedom-e-sdk to upload software with BOARD=freedom-e300-arty, openocd can connect it, just the ID is not matched.

Error: JTAG tap: riscv.cpu expected 1 of 1: 0x10e31913 (mfg: 0x489 (SiFive, Inc.), part: 0x0e31, ver: 0x1)
Error: Trying to use configured scan chain anyway…
Warn : Bypassing JTAG setup events due to errors

It also failed to upload flash with openocd:
Error: Device ID 0x20000913 is not known as FESPI capable

I just wonder how the Device ID is related to FESPI capability, can some one show me where to modify it in openocd software?



Solved…just found the answer in another thread, please ignore this problem.

# flash bank my_first_flash fespi 0x20000000 0 0 0 $_TARGETNAME
